A Japanese girl (or even a guy) that uses native English speakers for free English Lessons.
Eigo Bandits have no interest in their conversation partner treating them as pets to show off and make pay for dates & coffee that they invite themselves to.
Eigo Bandits only want to speak in English because they do not care for you to learn Japanese.
